Inter-rater Reliability of the Reflux Finding Score Among Gastroenterologists

Title:

Inter-rater reliability of the reflux finding score based on endoscopic laryngeal findings in the diagnosis of laryngopharyngeal reflux disease

Participants:

Voluntary participants after invitation among members (a total of about 40 gastroenterologists) of Gangwon Branch of Korean Society of Gastrointestinal Endoscopy and an otorhinolaryngologist

Primary endpoint:

Interrater reliability (Kappa coefficient) on the sum of reflux finding score more than 7 points between an otorhinolaryngologist and gastroenterologists (7 points means the cut-off value for the diagnosis of laryngopharyngeal reflux disease)

Secondary endpoint:

Agreement (%) on 8 items of reflux finding score for laryngopharygeal reflux among gastroenterologists

About this study

Study Design

Recruitment of doctor participants: introduction by e-mail
Education on reflux finding score - standardized materials (instructional video)
PRETEST (15 pictures) / feedback (at-a-glance assessment format)
TEST 1 (50 pictures) - Acess format including 8 items at each pictures
Feedback education (individualized intruction of an otorhinolaryngologist)
TEST 2 (50 pictures) - Acess format including 8 items at each pictures
Test-Retest reliability - repeat Test 2 with 1 week interval (Participants should take retest of TEST 2 with the concealment of the answer)

Treatment and study plan

Primary outcomes

Cohen's kappa coefficient

Time frame: 5 months

Cohen's Kappa coefficient based on the sum of reflux finding scores (7 points or more than 7) for the diagnosis of laryngopharyngeal reflux disease between an otorhinolaryngologist (reference) and participant gastroenterologists

Secondary outcomes

Agreement (%) at each item out of 8 items of reflux finding score

Time frame: 5 months

Agreement (%) at each item out of 8 items (subglottic edema, ventricular obliteration, laryngeal erythema, vocal cord edema, diffuse laryngeal edema, posterior commissure hypertrophy, laryngeal granuloma, thick endolaryngeal mucus) of reflux finding score
